Samsung is the only Display maker who has used Cad Free QD's up to this point thru their licensing thru Nanosys. I've read several things that make me think Hansol uses Samsung technology - not Nanoco technology. For example, this article says they use Samsung patents: http://www.pressreader.com/korea-republic/the-korea-times/20150403/281835757209322 Besides, didn't Samsung come out with QD TV's before Nanosys had Cd-free QDs?
